$59 A/C Tune-Up, Inspection per unit
The contactor is the high-voltage switch that starts your AC compressor. When it fails — and in Arizona heat, it fails often — your system won't start, won't stop, or starts damaging your compressor. Bradford fixes it same day with a free tune-up included.
4.8· 280 Google ReviewsWhen Bradford replaces your contactor, we'll perform a full 20-point AC tune-up at no extra charge — refrigerant check, airflow test, temperature split, capacitor test, and a full system inspection. Normally $59, yours free when you book a contactor replacement.
When a contactor's contacts are pitted or the coil is weak, the contacts can rapidly open and close — a condition called "chattering." Each chatter event sends a voltage spike through the compressor windings. Over hours or days, this causes the compressor to overheat and fail. A compressor replacement costs $1,200–$2,500. A contactor replacement costs $195–$325. If you hear buzzing or chattering from your outdoor unit, call Bradford now.
Contactor failure is the second most common AC repair call in Arizona. Recognizing the signs early can prevent compressor damage.
The outdoor unit is completely silent when the thermostat calls for cooling — open contactor contacts.
The system runs continuously even when the thermostat is satisfied — stuck-closed contactor contacts.
Rapid clicking or buzzing from the outdoor unit means the contacts are arcing — urgent, can damage the compressor.
A failing contactor can cause voltage irregularities that trip the circuit breaker.
Pitted, burned, or discolored contact surfaces are a clear sign the contactor needs replacement.
A worn contactor with high contact resistance causes voltage drop, making the compressor labor to start.
Most HVAC contractors install whatever contactor is cheapest. Bradford installs quality contactors rated for Arizona's heat and cycle demands. Here's why it matters.
| Feature | QUALITY CONTACTOR What Bradford installs | CHEAP IMPORT What most contractors use |
|---|---|---|
| Contact Material | Silver-cadmium alloy — high arc resistance | Cheap alloy — pits and erodes faster |
| Typical Lifespan in AZ Heat | 6–10 years | 2–4 years |
| Failure Mode | Gradual wear — usually caught at tune-up | Sudden failure — often on hottest days |
| Risk to Compressor | Low — clean contact closure | High — arcing causes voltage drop & heat |
| Coil Voltage Tolerance | Wide tolerance — handles voltage swings | Narrow tolerance — fails in heat |
| Max Operating Temperature | Rated for AZ ambient conditions | Often under-rated for desert heat |
| Cost Per Year of Service | ~$20–$30/yr over 8 yrs | ~$50–$80/yr over 2–3 yrs |
| Risk of Compressor Damage | Very low | Moderate to high if contactor chatters |
A generic imported contactor might cost a contractor $12–$20. But when it fails in 18 months — chattering and arcing against your compressor — you're paying another service call, another contactor, and potentially a compressor repair. Bradford charges a fair price for a quality part because we don't want to see you again for the same problem.
